Just got an email, they are all out. The listing was wrong. Damn it. I want to BT like 5 more atleast!

 

 

Looks like the next one I do will be just the A2DP chip from China. They run about $5 each.

That's really odd, because there were multiple sellers selling this, some even selling two per listing at a discount, now they're all gone. I wonder if it was the same seller with different user names.

Anyways that's off topic so I'll stop it there.

I think unless that same module drops, I'll probably eventually try the chip like you mention, with maybe an old car phone charger module as my 12v to 5v converter.

You are right though, I saw more than a handful for sale a week ago and discounted multiple purchases..... What is going on??? Lol


I just hate that the china modules will take forever to get here, boo.

Oops I did it again! Another M70 showed up today yippie!!!!



I found a different supplier for the 12v ready bluetooth module like the one that was price jacked on ebay.

I'll install and give full review on this M70 after I bring it back from the dead.

Thanks guys. Hopefully the BT module will be here early next week. I still need to patch up my spare front case and paint it.


I might go custom with this color.....

Finished transplanting the guts.

Shined up the switches, rings, and plexi.

Fresh paint on the grills.


I also decided to fix the cracks on this case because the front is so mint. I will only have to paint the sides. Someone tried gluing the crack at the bottom and it made the crack fit together like crud. I had to scrape and sand the glue out before using acrylic cement.

So awesome that this new BT module showed up already. Even better that this one is in a hard plastic case so I was able to open it and check out the goodies!!!!

 

 

It looks like the BT module chip is piggy-backed to the voltage regulator board so you can pump 12v into it direct instead of the 3v-5v the module needs.

$30 on this one from Amazon.

 

I will give a full review/test of it later tonight. I won't know the range until it is in the boombox and finished. Maybe I can buy in bulk to offer the modules here for cheaper.

 

 

 

 

 

 

EDIT, WTF - the company already bumped the price from $30 shipped to $35 shipped!!!!!

Some progress.

This new BT module doesn't make any sound when you turn it on. That was a great feature on the last box. So I added blue LEDs that will light the VUs when the BT is on.


I also desoldered the REC/MUTE switch and used the board and metal bracket and soldered a new switch in its place. Lines up better with the top plate hole for the button.

I just need to figure out why the M70 doesn't power on until I use a cassette function. And sand the side panel and repaint that small area.

So where did you get a switch for this one? I know the first was almost a direct replacement with a 922 I think you said. How but this one?

The 922 had 3 switches that were perfect. 1 I used for my discolite power switch and the last 2 went into the M70s. I will buy one of the ebay switches and review it on the next BT M70 in my collection that I will keep.

You are quickly becoming the BT master and this is the BT thread that EVERYONE needs to read before trying this!

It all started with you man. I wouldn't have even tried using a rechargeable BT dongle.

Ever since then I have wanted a better option. My courage to try this on a popular box finally got to me and off I went.


I'm glad the technology has advanced to a level that I like.


Now, I ordered a 3rd style of BT module today. I will be getting a small stock of switches (because I have 4 M70's I still want to BT).

I can't wait to test, review, and compare the 3. I already see huge differences in the first 2.

The first 2 BT M70's were bought to install, test, and sell.


After I decide what BT module I like best, then I will start to BT a lot of my blasters INCLUDING the OG TDK 2 speaker, JVC M90, JVC M71, and a handful of others.
